Reality TV star Kim Kardashian spent part of Friday in San Francisco's Golden Gate Park, cheering on husband Kanye West as he performed at the mammoth Outside Lands Music and Arts Festival.

Kardashian posted a photo on Instagram from the show, which she then tweeted out to her nearly 23 million followers. The tweet simply read "Yeezus" (the name of West's most recent album), with a hashtag of #outsidelands. West also mentioned from the stage that his superstar wife was at the festival -- news that had the capacity crowd buzzing.

Kardashian also posted a scenic ocean shot on Instagram on Saturday, reading "Good Morning San Francisco."
